To all whom it may concern/.-

Be it known that I, JOHN E. MARSHALL, a citizen of the United States, residing at VBuffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Double-Address Envelopes; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andv use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked "thereon, which form a part of this specification.

My invention consists, broadly, of an envelope having a single y of substantially the size of the envelope, and two addresses placed upon such envelope in such a manner that t when the iiy is folded over upon itselfor un folded either` one 'of the two addresses is brought into view, while the other is hidden,

' so that the envelope is thus' adapted to be sent back and forth between two parties until it is rendered unfit for use by wear.

, I will now proceed to more `fully describe the manner in which I have carried out my invention.

Fig. 3 shows a finished envelope with one of the addresses exposed to view. Fig. 4k shows the same envelope with the other address exposed.A Fig. 5 is a section taken on the line a: a', Fig. 3, and Fig. 6 is a section taken on the lineyy, Fig. 4. Referring to the drawings, a is one ofthe sides of the envelope, 'and a the other side.

'b b are attachingflaps, and c is the fly, which is substantially of the size of the `portion a. d is a strip or re-enforce` of muslin or other thin cloth, which is secured to the inside of the blank before it is' folded, and is intended to cover the lines e e and e e, along which the. flyl is folded and unfolded, as will bemore fully hereinafter described. j is the tape with which the envelope is tied, which tape passes outthrough theside a of the envelope at the points ff.

In Fig. 1 the form of blank is clearly shown, and in Fig. 2 the side a is shown as having secured along its side edges by the flaps Z1 b. The envelope thus far constructed is then fold to be brought over upon the side a. The ily c is neXt folded along the line e" e', which exof the two permanent addresses which are to be placed upon the envelope is eitheriwritten,

half of the outer surface of the iiy, as clearly shown in Fig. 3. The other address is similarly placed upon the lower half of the side a, as clearly shown in Fig. 4.. As these two addresses are both on the same side of the blank, theycan be printed at the same tiine before the blank is folded. In' this instance I in sending vouchers and other papers back and forth between a station-agent and auditor of a railroad company, the address of the station-agent being placed upon the fly c and that of the auditor upon ithe side a. Whenthe envelopeis to be sent to the station-agent, .the

secured by the tape f, exposing the address of asshown in Figs. 3 and 5. When it is desired to return the envelope, with inclosed papers, to the auditor, the fly c is folded in upon itself, and in that position'A secured against the side aby the tape f, tlius concealing the address auditor, as shown in Figs. 5 and 6.

The re-enforce d is to be employed where the nature of the paper renders it necessary often folded and unfolded.

It is apparent that both addresses might be placed upon the fly-one address, as already shown, uponthe lower half ofthe outer sul face-of the fly, and the other upon the lower half of the inner surface-without departing from the spirit ofmy invention, as by turning the lower half of the iiy upon its upper outside half the addresses could be changed. The

one VI prefer.

I claimy 1. An envelope having a single y of ,sub` stantially the size of the envelope and two ad-v l ed along the line e e, which permits the fly c" have shownthe envelope adapted to be used ily c lies unfolded over the side a', where it is been folded over upon the side (t, and there ltends across the Hy at or near its center. One

printed, or otherwise placed upon the lower x the agent and concealing that of the auditor, y

ofthe agent and bringing ,to view that of the to strengthen 'the lines upon which the fly is form shown in the drawings is, however, the.

dresses placed upon such envelope in such a manner that when the fly is folded over upon itself or unfolded either one of the two addresses is brought into view, while the other 5 is hidden, as and for the purpose stated.

2. The envelope having the single iiy c, of substantially the sizeof the envelope, with an address placed upon the lower half of its outside surface, and another address placed upon the lower half of the side a of the envelope, the ily c being adapted to be folded in upon itself or unfolded, and secured in either position by the fastening device f, as and for the purpose stated.

I5 3. The envelope having,` the fly c, re-enforced by the strip d, as shown, and provided with an address placed upon the lower half of its voutside surface and another address placed upon the. lower half of the side a of the envelope, the fly c b'eing adapted to be 2o
